Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE ALBERT EDWARD HODGSONAND NORMAN CLARKE JONES, OF LONDON, ENGLAND APPARATUS non GENERATING on.GAS

Application fi1ed March 16, 1927, Serial No. 175,878, and in GreatBritain May 31, 1926.

This invention relates to apparatus for the generation from heavy oilsof oil gas that can be used as the fuel suppl for internal combustionengines of automo iles, tractors, agri- 5 cultural sets, quarrying sets,small marine craft, stationary plants and the like, or for use forheating purposes for furnaces and the like. 7 v

The object of the invention is to design such 10 apparatus that willwork on the suction gas principle, simplify the construction so that'worn' parts can be easily replaced and which will be "readily portable,to provide means whereby the gas emitted from the generator shall becooled to some extent by the incoming airwhich is used for the gasgeneration or for supporting'the combustion of the fuel, the apparatuscomprising a generator into which the oil fuel is regulatably fed and isvaporized on inclined perforated bafile plates disposed within thegenerator.

In the annexed drawings is diagrammatically illustrated apparatusconstructed in accordance with the present invention in which Figure 1is an elevation of the complete apparatus or assembled parts, theapparatus for cleansing and mixing the gas forming the subject matter ofa co-pending application for patent Serial No. 249,982, dated JanuaryFigures 2 and 3 are sectional elevation and plan views respectively ofthe generator.

Referring now to thedrawings, in which similar reference charactersrelate to like parts in all the figures thereof, the entire assembledapparatus is illustrated in Flgure 1 in which G represents the oil gasgenerator, S the scrubber and M the mixing chamber and filter thedetails of the generator being more particularly hereinafter described.I

The oil gas generator G is illustrated 1n Figures 2 and 3 and comprisesa steel receptacle a that is open at the top and fitted internally atits bottom with an angular flange b that forms an annular chamber 0.This annular chamber 0 is provided with a number of holes 0 that serveas air passages for the admission of air as will be hereinafter de- 59scribed. Beneath these holes 0 and resting w ithsuitable holes thatconstitute baflies or distributing plates within the gas generatingchamber for the fuel.

The steel casing terminates in a flange g situated at some distanceabove the top of the lining and in the space between thetop of thelining and the flange g is provided an oil heating coil 71, hereinafterreferred to,-whilst on the side of the casing a is or are provided w abranchor branches 2' for the gas exit from the generator G.

The annular chamber 0 at the bottom of the generator is provided withtwo air admission tubes 7' one of which passes through the gas A exittube 70, these air admission'tubes j are 175 open to the atmosphere andare provided with any suitable valve m for regulating the admissionofair which is drawn into the gas generating chamber through'the tubes jby the suction of the engine that is connected ,with the conduit 11, butis not shown in the drawing.

On the top flange of the casing or druma is fixed. a cover plate 02provided with a readily movable lid 0 and through the cover plate inpasses the oil inlet pipe 19 which is connected to the coil h situatedbetween the cover plate n and the top of the lining 6 so that theoilpassing from the coil h is heated by the exit gases. The heating coil hterminates in a depending pipe or jet g through which the oil 7 passesinto the gas generating chamber. The supply pipe, having a verticalextension 1' Ithatalso passes through the cover plate a v and serves forthe purpose of cleaning the jet '9. The oil inlet pipe is connected witha needle valve 8 which'is connected to the throttle of the enginetheconnection being so regu lated that when the throttle is opened theneedle valve allows the admission of the 00 quantity of oil necessaryfor the engine requirements.

The oil inlet pipe 19 is also provided with the valve t which can be setat a fixed feed, this valve being normally used for stationary engineand furnace operation. The needle valve 8 and fixed feed valve t areconnected to a suitable oil storage tank fixed so that oil will flowthereto by gravity by way of pipes u and a.

The casing of the generator is provided with a door c which affordscommunication with the interior thereof for cleaning and inspectionpurposes. Below this door there is fixed in the gas generating chamberan oil jet or burner provided with the needle valve 2 which can beoperated by hand. This burner w is used for starting up purposes.burrounding the needle valve 2 is an air pipe 3 provided with a T piece4:, one branch 4? of which is open to the atmosphere and provided withany suitable means for regulating the admission of air thereto. Theother branch of the T piece 4 is connected to a small supply tank 5fitted with a small hand pressure pump 6 while a suitable regulatingvalve is provided in the connecting pipe 4 This tank 5 may forconvenience be fixed on the cover a of the generator G.

The oil jet w is connected by the pipe 8 with a smallsupply tank 8 whichmay be fixed upon the cover n of the generator or may be a compartmentof. the main oil supply tank. This tank or compartment is fitted with asmall hand pressure pump 9.

The gas exit 2' from the generator G is connected to a scrubber orseparating device S for purifying purposes, the apparatus forming thesubject matter of our copending application for patent aforesaid.

The method of operation is as follows Referring particularly to Figure 1of the drawings the door a and the lido are removed from the generatorand the needle valve 2 opened so that a thin jet of oil passesby way ofthe pipe 8 into the gas generating chamber through the burner to fromthe container 8. The jet of oil is ignited and a stream of aircompressed in the tank 5 is allowed to pass by way ofpipe 4? into thetube surrounding the burner w. This strean of air is controlled by valve7. When the generator becomes heated the door '0 and lid o are closed,the air regulator 28 opened and the throttle 31 closed. The regulatingvalves in on the admission tubes j are now set at a suitable opening anda regulated quantity of oil allowed to enter the generator G by means ofthe jet 9 the oil feed regulator being set for a fixed feed. The needlevalve 2 and the air valve 7 are nowclosed. The fan 17 is then rotateduntil it is found that the gas issuing from valve 28 Will ignite. Thethrottle 31 to Which is com ected the needle oil control valve is isnowopened ,to the extent necessary for i. e. oil gas and petrol, thepetrol being slowly tha t h a l, g est mati n te m n steady andcontinuous.

To facilitate the comprehension of the above explanation of working thepipe connections between the engine induction and the filter M are shownin plan above the filter M in Figure 1 and'may be summarized asfollows;-25 the exit from the filter M is connected directly to .thethrottle 31 to which is fixed the three-way piece 32.one branch of whichis connected to the engine induction 33, the second 34: to a controlthrottle and carburetter and the third to the throttle 31 as aforesaid,

What we claim is An apparatus for generating oil gas; comprising an oilgas generating chamberhaving an outer steel casing and an innerroflactory lining, inclined perforated baffle plates attached to therefractory lining within the gasifymg chamber an oil inlet c011 withinthe upper portion of the gasifying chamber above "the refractory lining,whereby the oil is preheated by the generated gas, an annular airadmission chamber at the base of the gas generating chamber, an airinlet pipe leading to the air admission chamber, and an oil gas outletpipe surrounding a portion of the air inlet pipe, whereby the airispreheated by the outlet oil gas.
